Asked the Charmhub team (cc @Roadmaster) for a clarification of what conditions triggers this, as it's something we've started seeing recently. And just to add; I've seen this myself, both locally and in CI, so there definitely is something going on here.

This is not an issue anymore in 2.0.0

For anyone stumbling into this in the future: this error message can appear if you are releasing more than one charm in the same repo.

The solution to avoid this error is to use different tag-prefixes for different charms, as documented here: https://github.com/canonical/charming-actions/tree/main/release-charm
